The reason I would not do it again is because there was little difference in trailer height for the money spent. As you can see from the “after” picture I posted, the trailer is still not level. However, it raised the camper enough that I need a 4th step and I lost 2” of leveling jack throw. My original concern over being nose high was the possibility of uneven tire, axle and suspension wear. In retrospect, these concerns may or may not have been legitimate.
I wouldn't despair too much over paying $2000.00 to get the lift. When I raised my trailer I think I paid in the $1500 range but this would have been 10 years or so ago. That lift gave me, I believe 7" of clearance, before that I had 5". Not quite enough! I think you said you had 7 1/2 now which meant you had 5 1/2 before. Again that's borderline.
Yes you might have been fine but then again your bed rails may have contacted the fiver and that would have ate your $2K really quick. Or left you with some damage to the truck and trailer. You are correct, nose high can also cause suspension issues and axle tire issues.
If cost is your main reason for the regret I would not sweat it.
You may have saved those initial costs and been forced to pay for other things further down the road.
Classic pay me now or pay me later scenario.
The pay me later scenario generally comes with even more stress, angst, and headaches.
